Abstract：With the acceleration of China's urbanization process,the urban heat island effect has become one of the prominent environmental problems.Urban green spaces,as the'cooling source'of the city,can effectively alleviate the urban heat island effect.Based on geographic information system(GIS)and remote sensing(RS)technologies,the surface temperature(LST)of the main urban area of Shenyang City in 2015,2018,and 2020 is inversely calculated,and the vegetation coverage(FVC)during the same period is calculated.The temporal and spatial evolution patterns are analyzed.Through the classification of heat island grades and buffer zone analysis,the spatial distribution and evolution characteristics of the heat island effect are quantitatively studied.Considering the background of population growth and urban expansion in Shenyang City,suggestions for optimizing the spatial layout of urban green spaces are proposed for the areas with concentrated heat island effects,providing references for the urban ecological planning and heat environment improvement of Shenyang City.
